Designed for professional use in pre-column systems for HPLC, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Gravity Sb, 5 μm, 4 x 2 mm feature base deactivated (BDS), high density octadecyl (C 18, ODS) modification. With a pore size of 110 Å and a specific surface area of 340 m²/g, these guard columns offer excellent separation performance. Featuring fully porous particles (FPP) and a carbon content of 13 %, they are suitable for acetonitrile-water eluents and have a pressure stability of up to 600 bar. Their endcapped design ensures optimal column longevity, making them ideal for protecting your main HPLC column from contamination.
